Java Programing laungage

In this example we are going to set background color of a PDF using java. In this example we are using setBackgroundColor(Color object) to set the background color.

There are basic five steps to create PDF:

We are creating and object of rectangle.We are passing this rectangle into Document to customs the page size.

Rectangle pageSize = new Rectangle(216, 720);

Step1: Creation of a document-object

Document document = new Document(pageSize);

Step2:Create a writer that listens to the document and directs a PDF-stream to a file.

PdfWriter.getInstance(document,
new FileOutputStream("LandscapePortrait.pdf"));

Step3: Open the document

document.open();

Step4: Add a paragraph to the document.We are adding the standard size of the page in diffrent unit.These values will added at PDF file.

document.add(new Paragraph(
"The size of this page is 216x720 points."));

document.add(new Paragraph(
"216pt / 72 points per inch = 3 inch"));

document.add(new Paragraph(
"720pt / 72 points per inch = 10 inch"));

document.add(new Paragraph(
"The size of this page is 3x10 inch."));
document.add(new Paragraph(
"3 inch x 2.54 = 7.62 cm"));

document.add(new Paragraph(
"10 inch x 2.54 = 25.4 cm"));

document.add(new Paragraph(
"The size of this page is 7.62x25.4 cm."));

Step 5: Close the document

document.close();

Example:

package com.itext.pdf.example.r4r;
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Paragraph;
import com.lowagie.text.Rectangle;
import com.lowagie.text.pdf.PdfWriter;

/***In this example we are going to customize the page size.
 */
public class CustomPageSize 
	{
/*** Creates a PDF document with a certain pagesize
 */
public static void main(String[] args) 
	{
System.out.println("Customization of  PDF PageSize ");
  
/Creating an object of rectangle to cutomize the PDF page size.
Rectangle pageSize = new Rectangle(216, 720);

/Step 1: Here we are creating of a Document object
Document document = new Document(pageSize);  
try {
/ Step2:
/ Here we are creating a writer that listens to the document
/ and directs a PDF-stream to a file

PdfWriter.getInstance(document, new FileOutputStream
("CustomPageSize.pdf"));

/ Step3:Here we are opening the document
 document.open();

/Step4:Here we are add some paragraphs to the document
/These paragraphs are the standard size of 
/the page in different unit.
document.add(new Paragraph(
"The size of this page is 216x720 points."));

document.add(new Paragraph(
"216pt / 72 points per inch = 3 inch"));

document.add(new Paragraph(
"720pt / 72 points per inch = 10 inch"));

document.add(new Paragraph(
"The size of this page is 3x10 inch."));

document.add(new Paragraph("3 inch x 2.54 = 7.62 cm"));
document.add(new Paragraph("10 inch x 2.54 = 25.4 cm"));
document.add(new Paragraph(
"The size of this page is 7.62x25.4 cm."));
}
  
catch(DocumentException de) 
	{
System.err.println(de.getMessage());
    }
catch(IOException ioe) 
	{
System.err.println(ioe.getMessage());
    }
  
/ Step5:Here we are closing the document
document.close();
 }
}
